Abstract
The present invention provides a process for producing a graphene-enhanced anode active material for use in a lithium battery. The process comprises (a) providing a continuous film of a graphene material into a deposition zone; (b) introducing vapor or atoms of a precursor anode active material into the deposition zone, allowing the vapor or atoms to deposit onto a surface of the graphene material film to form a sheet of an anode active material-coated graphene material; and (c) mechanically breaking this sheet into multiple pieces of anode active material-coated graphene; wherein the graphene material is in an amount of from 0.1% to 99.5% by weight and the anode active material is in an amount of at least 0.5% by weight, all based on the total weight of the graphene material and the anode active material combined.
